SPEED-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 716,456, dated December23, 1902. Application filed March 22, 1902. Serial No. 99,489. (Nomodel.)

To alZ whom, it may concern.-

Be it known that I, MORTON G. MILLER, a citizen of the United States,residing at Summit Grove, in the county of Vermilion and State ofIndiana, have invented a new and useful Speed-Regulator, of which thefollowing is a specification.

My invention is an improved speed-regulatorforengines, designedparticularly for trac tion-engines; and the object thereof is to providea device to be connected to the governor, so that the said governor maybe quickly and easily adjusted to increase or diminish the speed of theengine.

Another object of my invention is to provide an arrangement capable ofoperation from the cab of the engine, and thus permit ting of a readyadjustment while the machine is in motion.

Still a further object of my invention is to provide a device by whichthe operatingshaft may be firmly held to its adjusted position withoutthe necessity of a further operation other than operating the shaft.

\Vitli the above briefly-stated objects in view my invention alsoconsists in certain details of construction and novelties of combinationand arrangement of parts, as will be fully described in the followingspecification, and pointed out in the claims, reference being had to thedrawings, in which- Figure 1 is an elevation of a portion of asteam-cylinder having a governor mounted therein and to whichmyimprovement is applied. Fig. 2 is a detail perspective view of aportion of the bracket, showing the position and location of theoperating-gears. Fig. 3 is a detail view, partly in section, showing theadjustable connection of the screw to the valve-stem. Fig. 4. is adetail side elevation of the gears, illustrating a slightly-modifiedconnection of the operating-shaft. Fig."5 is a diagrammatic view showingthe operatingshaft supported by the rafters of the hood of the engine,and Fig. 6 is a detail view of the device for holding theoperating-shaft from turning.

My invention is designed to be connected to the ordinarycent-rifugally-operating governors, and in the drawings I have shownsuch style governor A mounted upon the piston-cy1inder B, and upon thebase of the cylinder I securely fasten a bail-shaped bracket 0, having asupplemental bracket C arranged thereon, in which, together with thecross-piece of the main bracket, is mounted a shaft D, carrying abeveled gear D, that is adapted to be engaged by a similar gear E,carried by the operating-shaft F,'the latter extending rearwardly intothe cab and is provided with a suitable hand-wheel F. This shaft F ismounted at its forward end in the said supplemental bracket and at itsrear end in one or more brackets G, carried by the engine and located atany suitable point.

The lower end of the shaft D is bifurcated, the members D havingvertically-arranged slots D produced therein, in which fit the studs H,carried by the head of the screw H, that engages the valve-stem, and byconnecting the screw to the shaft D in the manner just described thevertical movement of the screw is permitted without causing a verticalmovement of the gear-shaft.

Suitably mounted upon one of the brackets that supports theoperating-shaft is a locking device I, whose jaws I are arranged tostraddle the shaft and bear upon eitherside thereof, being held in suchposition byascrew J, carrying a thumb-nut J and by which the tension ofthe locking-jaws may be readily regulated. In practice the screw isadjusted so that the jaws will grip the shaft sufficiently to hold itfrom independent movement, but at the same time allowing the shaft to berevolved by hand.

When my improvement is applied to an engine carrying a hood, theoperating-shaft and supporting-brackets are supported by the rafters, asshown in Fig. 5 of the drawings; but the general arrangement of thegears and shaft is similar in every respect to the construction shown inFig. 1 of the drawlngs. r

In instances where the governor is located considerably above theplatform of the operator and it is necessary to run the operatingshaftto within easy reach I. usually arrange a universal joint in the shaft,which permits the shaft to be located at any angle desired.

In operation when it is desired to alter the speed of the engine it isonly necessary to turn the operating-shaft one way or the other, whichthrough the medium of the gears turns the adjusting-screw of thevalve-stem, and thereby raises or lowers it to regulate the speed, asthe occasion requires.

It will thus be seen that I provide an exceedingly cheap and simpledevice for accomplishing the result, as above specified.

Having thus fully described my invention, What I claim as new, anddesire to secure by Letters Patent, is

1. A speed-regulating device for engines, the combination of thegovernor, a bracket carried thereon, a supplemental bracket arrangedupon the first-named bracket, a shaft carried by the brackets and havingone end adapted for engaging the valve-stem of the governor, a gearcarried by the said shaft and an operating-shaft having a gear held forengagement with the gear of the first-named shaft, substantially asshown and described.

2. In a speed-regulating device for engines, the combination of thegovernor having a bracket mounted thereon, a supplemental bracketcarried by the first-named bracket, a shaft carrying a gear mounted inthe brackets, one end of the said shaft being bifurcated and engagingthe screw of the valve-stem, an

operating-shaft carrying a gear that is adapted for engagement with thegear of the firstnamed shaft, and means for holding the shaft in itsadjusted position,subst-antiallyas shown and described.

3. In a speed-regulating device for engines the combination of thegovernor, having a bracket mounted thereon, a supplemental bracketcarried by the first-named bracket, a shaft carried by the brackets andhaving a gear mounted thereon, one end of the said shaft beingbifurcated and the members thereof slotted and adapted for the receptionof the studs carried by the screw of the valvestem, brackets mountedupon the engine, an operating-shaft held by the brackets, a gear carriedby the operating-shaft and adapted for engagement with the gear of thefirstnamed shaft, and a holding device arranged upon one of the bracketsand adapted for engagement with the operating-shaft, substantially asdescribed.
